		$out .= '<code>Piwik_AddWidget( $widgetCategory, $widgetName, $controllerName, $controllerAction, $customParameters = array());</code> - Adds a widget that users can add in the dashboard, or export using the Widgets link at the top of the screen. See the example in the <a href="http://dev.piwik.org/trac/browser/trunk/plugins/UserCountry/UserCountry.php#L143">UserCountry Plugin file</a> or any other plugin)<br/>';

				<ul><li>The "token" parameter is the string unique key found in the translation file. For this token string to be available in Javascript, you must
				suffix your token by "_js" in the language file. For example, you can add <code>\'Goals_AddGoal_js\' => \'Add Goal\',</code> in the lang/en.php file</li>
				<li>You then need to instruct Piwik to load your Javascript translations for your plugin; by default, all translation strings are not loaded in Javascript for performance reasons. This can be done by calling the Smarty modifier before any your javascript includes that would be using the translations, eg. 
					<code>{loadJavascriptTranslations plugins=\'$YOUR_PLUGIN_NAME\'}</code>. In our previous example, the $YOUR_PLUGIN_NAME being Goals, we would write <code>{loadJavascriptTranslations plugins=\'Goals\'}</code>
					</li><li>You can then print this string from your JS code by doing <code>_pk_translate(\'Goals_AddGoal_js\');</code>.
					</li></ul>';

					You can easily force your widget to reload in the dashboard by calling the helper function <code>piwik.dashboardObject.reloadEnclosingWidget($(this));</code>.';
		
		$out .= '<h2>Smarty plugins</h2>';
		$out .= 'There are some builtin plugins for Smarty especially developped for Piwik. <br>
				You can find them on the <a href="http://dev.piwik.org/trac/browser/trunk/core/SmartyPlugins">SVN at /trunk/core/SmartyPlugins</a>. <br>
